PHP Exercises: Check if the value of each element is equal or greater than the value of previous element of a given array of integers

PHP Basic Algorithm: Exercise-130 with Solution

Write a PHP program to check if the value of each element is equal or greater than the value of previous element of a given array of integers.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
{ 
    // Iterate through the elements of the input array using a for loop
    for ($i = 0; $i < sizeof($numbers) - 1; $i++)
    {
        // Check if the next element is less than the current element
        if ($numbers[$i + 1] < $numbers[$i]) 
        {
            // If true, the array is not in ascending order, so return false
            return false;
        }
    }

    // If the loop completes without returning false, the array is in ascending order, so return true
    return true;
}   

// Use the 'var_dump' function to print the result of the 'test' function for different arrays
var_dump(test([5, 5, 1, 5, 5]));
var_dump(test([1, 2, 3, 4]));
var_dump(test([3, 3, 5, 5, 5, 5]));
var_dump(test([1, 5, 5, 7, 8, 10]));
?>

Sample Output:

bool(false)
bool(true)
bool(true)
bool(true)
